![]() ![]() ![]() ![]() The children can see how the 'abstract' grid method overlays the array and formalises the blank array into a standard form.ĭivision as the Inverse Operation of Multiplication Here, to work out 34 x 9, the child has decided to do 34 x 10 and then take off the 34 x 1.īeyond the blank array this 'dividing the multiplication into easy parts' strategy can be formalised into the grid method. The blank array helps children to use other strategies, such as compensating, when carrying out multiplication. Here's a child using the blank array, as a thinking tool, to help them work out 15 x 14. This means that children can use their known number facts to work out calculations.Īfter a while drawing all the dots can get very tedious! The blank array then becomes a very useful tool for helping children model their thinking and work out how to do more complex multiplications in an informal way. This representation not only assists in understanding the process, but provides a visual image forĬhildren to draw upon as they begin to use and memorise the basic number facts.Īrrays can be helpfully used to explore calculations such as 13 x 5 where the array can be split into useful chunks such as 10 and 3. For example, by progressively adding another column of three objects, children can build the three-times tables for themselves. Before drilling and memorising tables, children must understand how these facts are derived. The following array, consisting of four columns and three rows, could be used to represent the number sentence 3 x 4 = 12, 4 x 3 =12, 3 + 3 + 3 + 3 = 12 and 4 + 4 + 4 =12.Īrrays can be used for building multiplication facts in a meaningful way. Each column must contain the same number of objects as the other columns, and each row must have the same number as the other rows. We use the power of the iPad and technology to empower teachers and help children understand and learn key math concepts and to unravel misunderstandings.Jennie Pennant, with the help of Jenni Way and Mike Askew, explores how the array can be used as a thinking tool to help children develop an in-depth understanding of multiplication and division.Īrrays are useful models for multiplication which can be used in a variety of ways, ranging from highly structured lessons to games and open investigations.Īn array is formed by arranging a set of objects into rows and columns. Our apps are research based and classroom tested to make sure they help children learn. Math Slide is part of our ‘play and learn’ series, which are games high in educational value where children learn as they play. Learning math should be fun and exciting, a rewarding adventure.Playing educationally rich games and apps improves understanding.Our apps range from learning to count up to understanding and using fractions and decimals, with each app focusing on one key concept. We develop apps that focus on the key concepts that need to be fully understood to progress and succeed in mathematics. Maths Adventures Limited is a New Zealand company helping children learn mathematics. Game 10 – triples of number facts: 6 + 5 + ? = 15 Game 9 – pairs of number facts: 6 + 7 = 8 + ? Game 7 – addition & subtraction facts up to 10+10 Game 4 – representing number facts up to 10+10 Game 3 – doubles up to 10, pairs that equal 10 Game 2 – doubles up to 10, pairs that equal 10 Game 1 – representing doubles & pairs to 10 Slide a tile into the center to match the image, answer or equation Press ‘Start Game’, wait for the count down, then playĥ.
